M���� <br /> Working To Restore Nature <br /> Three borings (SB3, SB4 and SBS) were drilled to depths of 24 5 to 26 feet Hydropunch <br /> groundwater samples were collected from borings SB3, SB4 and SBS Cored soil samples were <br /> ' collected for lithologic description above the water table at 5-foot intervals and below the water <br /> table at selected intervals in accordance with RESNA's Soil Sampling Protocol (RESNA, May <br /> ' 4, 1994, Workplan for Additional Site Investigation, Appendix I) Two soil samples were <br /> collected for laboratory analysis from SB3, one from a depth of approximately 15 feet and a <br /> ' second sample from approximately 20 feet below surface grade The sampling attempt at 25 to <br /> 26 feet in this boring resulted in incomplete recovery. Three soil samples each were collected <br /> ' for laboratory analysis from SB4 and SBS, one from the upper capillary fringe soils and two <br /> from depths at which impact was noted in previously installed bonngs The location of the <br /> ' borings are shown on Figure 2 <br /> Cored samples were collected in brass sleeves with a modified California split spoon sampler <br /> Sample sleeves were sealed with teflon tape and a plastic cap, sealed in plastic bags and <br /> transported to the laboratory under strict chain-of-custody on ice in an airtight cooler Samples <br /> t were analyzed for BTEX by EPA method 8020 and TPHg by EPA method 8015 by Sequoia <br /> Analytical Laboratory (cert no 1210) The samples from the Madison Street site were also <br /> ' analyzed for TPHd (EPA method 8015) and HVOs (EPA method 8010) <br /> ' All drill cuttings are stored on plastic sheeting, covered with same, and retained on-site pending <br /> laboratory analysis of samples for characterization for disposal <br /> prevent cross-contamination the augers were steam cleaned between s The bonn <br /> Top g g <br /> ' decontamination water is stored on-site in approved 55 gallon DOT drums pending laboratory <br /> analysis <br /> 1 <br /> The monitoring wells were constructed of 4-inch diameter F480 PVC well screen/casing and <br /> ' completed as shown on Figure 3 Well screen slot size is 0 020 inch, and filter pack is 2/12 <br /> p <br /> jM0'7p1}MRTS8 <br /> %SR-06%FNL <br />
